FEED-ROLLER GEAR FOR WOOD-PLANERS.

SPECIFICATION forming part of Letters Patent No. 267,947, dated November 21, 1882.

Application lcd July 27, 1882. (No model.)

To all whomit may concern:

Beitknown that I, PAUL STOERGER, of Ghicago, Cook county, Illinois, have invented a new alud Improved Feed-Roller Gear for Wood- Planers, of which the following is a full, clear, and exact description.

My invention consists of a chain-belt contrivance to be used in substitution of the toothed gears now employed, by which economy ot' driving-power will be effected, and a wider range of adjustment is providedfor the upperrollers, and other advantages are gained, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part of this specication, in which similar letters of reference indicate corresponding parts in both figures.

Figure l is a side elevation of a planingmachine having the feed-roller gear of my invention applied to it, and Fig. 2 represents details of the said gear.

I use'an endless chain, a, in substitution of the gears, running it from the driver b to the left of the feed-roller pinion o, thence to the right, over roller-pinion d, thence over rollerpinions f g, and back over roller-pinions h t', thus connecting it so as to turn the respective rollers inthe right direction, and by passing it between rollers c and d, as stated, ob-

n, of any approved form or arrangement, to keep it in position. The bar l has a pin-hole, p,.and a pin, q, is provided for holding up the weight whenever it may be required to take ofi' the tension for any purpose.

It will be seen that the slack of the chain under ti ghtener j will vary as the height of the upper feed-rollers varies, and that the extent of such slack may be such as to allow a wide range of variation to the rollers for different thicknesses of lumber.

It will also be seen that several intermediate pinions and their bearings and other adjuncts will be dispensed with by this chain contrivance, and it is believed that the friction will be materially lessened.

I am aware that there has been heretofore a mechanism for operating feed-rollers, consisting of a stationary drive-wheel, a spurwheel,. an adjustingwheel, and an endless chain; but V What I claim as new and of my invention 1s- The combination', with the driver I), the superposed feed-roll pinions o d, and the rollerpinions f i g h, parallel to the feed-rolls, of the endless chain a, passing up from the side pulley of one feed-roll pinion diagonally across and over the other, then straightpver the side pulley of the roller-pinionf, then under the tightener j, then over the side pulley of pinion g, then around the tightenerk, then straight over the side pulleys ot' pinions h z', and then back to the side pulley of driver b, as described.
